Hi all,

I have read and try quite a lot on this, alas it is still not working.

I have 2 IDE HD (hda = Fedora, hdc = windows data) (don't ask me why it is not hdb..) and one Sata Hd (sda = windows, 2 partitions).

I boot on the IDE drive and get Grub... no problem for launching Fedora, but Grub refuses to collaborate for windows.

.. I'm getting desperate on this... any help would be GREATLY appreciated!!!

I have no experience with SATA drives.
I do have experience with GRUB.
Because hda is in the primary master slot and hdc is in the secondary master slot? hdb would be in the primary slave slot.

It looks like GRUB is set to boot your Windows data partition instead of your Windows OS.

I am not sure exactally what the entry should be but comment out what is there now and try pointing GRUB to your SATA drive on sda.

There could be an issue with drivers at boot too, as I said I have not used SATA drives.

According to what was posted, the SATA drive with Windows is hd2. If the boot files are in the first partition as is usually the case, the "rootnoverify" should be (hd2,0), not (hd0,0) which is the Fedora drive's first partition. Everything in the grub menu.lst looks good except for that.

I think you are correct and I feel silly for missing the clues under the device.map heading and instead thinking GRUB counted the drives like Linux skipping the missing hdb as hd1.

Yes!!!! THANK YOU VERY MUCH!!!
I tried with only rootnoverify (hd2,0) and it hangs... but if I keep the mapping AND use hd2,
map (hd0) (hd2)
map (hd2) (hd0)
rootnoverify (hd2,0)

then it works perfectly!!
... I don't understand why, as with the mapping hd2 (win) is now hd0 (linux)... and in the bios the Sata drive is the 2nd one but at least it works well!!

Thank you again!
Solving in 5 minutes a problem I've fighting with for a few days makes me want to learn more!!!

Have a good day,
Jean
